Hundreds of frenzied teenagers mobbed pop star Justin Bieber as he arrived in New Zealand, knocking down his mother and stealing his hat as he was rushed through the airport to escape the fans.

The heartthrob Canadian singer tweeted his 2.1 million fans Wednesday to report: "Finally got to New Zealand last night. The airport was crazy. Not happy that someone stole my hat and knocked down my mama. Come on people."

The star's mother, Pattie Mallette, tweeted that she was "OK" after being pushed over by rampaging fans at Auckland Airport.

"Thanks for all ur support!! I'm ok thank you!!!," she wrote.

He earlier told fans that he wanted to sign autographs and have pictures taken. But police and security had to shut the opportunitydown because fans were pushing.

The frenzy followed similar scenes in Sydney, Australia, earlier in the week, where police canceled a Bieber concert after surging crowds crushed some fans. The most serious injury was a fractured kneecap.

A similar situation occurred at a mall in Long Island, New York, in November. Bieber's free concert was canceled at the 11th hour when hundreds of fans stampeded after a reported sighting of the teen star.

In New Zealand, a mob of mainly teen girls screamed their welcome and swarmed toward Bieber, 16, at the airport. Escorted by security, police and minders, Bieber quickly left the airport out a side door.

A waiting black SUV whisked him away from the frenzied crowd, leaving some sobbing with disappointment.

After Bieber's departure, teen Tory Shaffett said she was having trouble breathing.

"Oh my god, he was so amazing and beautiful. I can't believe I saw him," she told reporters.

Bieber bungy jumped off Auckland Harbor Bridge on Wednesday and posted footage on his Twitter account.
